@Cresion Breezes
Thanks for the questions~~
No held items. I feel as tho they would cause troubles and make the game a little more complicated
I suppose healing during battle is okay, but that's about it. and obviously no spamming. I'll put a limit on healing items after i think about it. No X items. At lvl 100 they aren't really needed
PP is there, but it also isn't. As long as you don't spam super moves and use a healthy balance of the other moves too, i wont need to put a limit.
No EV/IV/Hidden Power (trying to keep this as simple as possible)
HMs aren't needed. If a pokemon can fly it can fly. If it can swim it can swim. If it's strong enough to push/break boulders it can. Etc.
No natures, and abilities that make no sense are irrelevant same with moves that make no sense.
The backstories CAN be similar to the game's plots but it is by NO means required
Friendship/Affection with Pokemon is a given since they've been with you through your entire journey
Don't worry backpacks will have game physics (so yes xD)
